T0 all whom it may concern.-

Beit known that I, LONGLEY LEwIs SAGEN- DORPII, of Cincinnati, Hamiltoncounty, Ohio, have invented certain new and useful Improvements inMachines for Making Metallic VVeather-Boarding or Clapboarding, of whichthe following is a specification.

The various features of my invention and the advantages resulting fromtheir use, conjointly or otherwise, will be apparent from the followingspecification.

In the accompanying drawings, Figure l is a front elevation of themachine with the dies down. Fig. 2 is a front elevation of the machinewith the dies raised. Fig. 3 is an elevaticn of the left-hand end of themachine, as shown in Fig. 1. Fig. 4 is a top View of the right-hand endof the machine, as shown in Fig. l, the top being removed. Fig. 5 is acentral vertical section of one of the dies. Fig. 6 is an elevation ofthe series of cams, taken from the rear of the machine. Fig. 7 is anelevation of the front cam, looking from the rear ofthe machine. Fig. 8is a perspective view cfa sheet of metal weather-boarding produced by mymachine.

The machine is supported on a frame-work consisting of the end pieces,A, united by crosspieces C at the top and the bed-plate B at the bottom.The upper surface of the bed-plate B i's provided with parallel angularridges b, which extend across the entire width of the machine. The shapeof the top of the bedplate is the same as the shape of the product ofthe machinea sheet of metallic weatherboarding or clapboarding, as shownin Fig. 8.

The machine is provided with dies D, preferably five or six, being oneless than the number of ridges b. The dies lie in juxtaposition andextend entirely across the machine, their ends bearing against the endpieces, A, which form the guides for the dies. The lower face of eachdie is made to f1t in one of the grooves between two adjacent ridges, b.The front die is provided with a lip, d', which fits over the firstridge, b, as shown in Fig. 3. Each die is separately provided with meansfor raising and lowering it. Each die is provided with one ormorewpreferably three-upwardpreferably arranged so that the top of allthe shanks of all the dies lie in the same horizontal plane. Over eachdie is a horizontal bar,

F, which is hung from the top ofthe machine by a series of shortconnecting-bars, E', which 55 are pivoted to the top of the machine, andalso to the bar F. Similar connecting-bars, E, attach the horizontal barF to the shanks d. There is provided for each die a series of springs,G, attached to the die below and to 6o the top of the machine abovewhose tendency is to raise the' dies. There is also provided for eachhorizontal bar F a spring, H, which is attached to the bar F and to somepart of the frame of the machine, preferably the top, 6 5 which is tothe right of its attachment on the bar F, as shown in Figs. l and 2.These springs draw the bars F to the right and keep them againstthefaces of their respective cams, to be described presently.

The combined actions of the springs H and G are to draw the bars F tothe right and to raise the dies D. The right-hand end of each bar F isprovided with a roller, f, preferably supported as shownin Fig. 8. Thecam-shaft I extends across the right-hand end ofthe Inachine, as shownin Figs. l and 2, and is supported therein appropriate brackets. Thisshaft I carries a series of cams, J J2 J3, Ste., one for each bar F.

The cam J is shown in Fig. 7. The part j* of the face of this cam is aperiphery ofa circle, whose center coincides with the center of theshaft ou which the cam is mounted. At the pointj the face of the camlies in a radius of the circle and extends in to the hub j* of the cam.The circular periphery of the hub ja forms the face of the cam for abouta quarter of a circle, and the rest of the face of the cam is made up bythe part j', a gentle curve eX- tending from the edge of the hub j3 tothe point j?. In the rst cam, the part j* preferably extends throughasemi-circumference. In each succeeding cam, however, the part j* isshorter-that is, in each cam the part jJt is shorter than in the camprecedingit and longer than in the cam following it. The cams arearranged upon the shaft I so that the points j ly-projecting Shanks, d.These shauks are 5o of all the cams lie in the same radial plane of theshaft.

Fig. 6 is an elevation of the whole series of cams, taken from the rearof the machine, and showing the projection of each cam on the onepreceding it.

Any suitable mechanism may be adopted for operating the cam-shaft, apreferred form the bar F.

being shown in Figs. l, 2, and 3. One end of the shaft I is providedwith a spur-wheel, I', which meshes with a pinion, la, on acountershaft, K. The counter-shaft K is provided with one or twocrank-wheels, L, each having a handle, Z. On the front of the bed-plateB two adjustable stops, M, are placed.

The connecting-rods E E' are made adjustable in length, and thepreferred means of accomplishing this is by a right and left hand screw,as shown in Figs. l and 2. rlhe rods E, attached to one of the dies, andthe rods E', corresponding thereto, constitute the links of a series oftoggle-levers. For convenience, the proximate ends of these levers arepivoted to The movement of the bar F in the general direction of itslength will straighten gr dex this joint, and thus depress or raise thThe mode of operation is as follows: Starting with the'dies raised, asshown in Fig. 2, the plate of sheet metal to be shaped is placed on thebed-plate B,with its front edge against the stops M. The cranks L arenow turned, so as to move the crank-shaft in the direction of the arrowin Fig. 7. The cams at starting are in the positions shown in Fig. 6with reference to the horizontal bars F, and the latter are in thepositions shown in Fig. 2. As the camshaft rotates, the first cam, J',strikes against the roller f of its bar F, and gradually moves this barto the left until the point j of the cam rests against the roller f.When this point is reached, the bar F remains stationary until the pointj of the cam has passed the roller f,when the springs Gand H, attachedto this particular bar F, comes into play and throws the bar F suddenlyto the right, so that its roller f rests against the periphery of thehub of the cam. By reference to Figs. l and 2 it will be seen that asthe bar Fis moved to the left it gradually lowers the die D, attached toit, and when it has reached the position shown in Fig. l it hasdescended far enough to press the sheet of metal onto the rst ridge b ofthe bedplate. As the bar F moves to the right the springs G raise thedie D. Now, by reference to Fig. 6, it will be seen that the dies,cornmencing with the first, are made to descend in regular order oneafter the other. As each additional fold in the sheet of metal isproduced the width of t-he sheet-that is, from front to rear of themachine as it lies on the bed-plate-is lessened. If the diesshould alldescend-at once, the sheet would not have an opportunity to shorten, andwould in consequence be torn. The points] of all the' cams pass therollers f at the same time, and consequently the dies are all releasedat once and are raised together. The shaped sheet of metal is nowremoved and a new sheet of metal inserted, and the operations justdescribed are again repeated.

What I claim as new, and desire to secure by Letters Patent, is-

l. In a metalbending machine of the character described, thecombination, with the bed-plate having parallel ridges, of the diesD,one less in number than the ridges on the bedplate, the front dieprovided with a lip which fits over the front ridge of the bedplate, anda series of cam mechanisms, substantially as described, whereby thefront die is iirst depressed to form and retain the edge of the stripoperated on and the dies toward the rear are depressed in succession,substantially as de scribed.

2. The combination, in a metalbending machine, of a bed-plate having aseries of ribs, a series of dies above the same, and a set ofconnecting-bars, E E', attached, respectively, to the frame and to thedies, each bar E E being eXtensible in length, the horizontal barpivoted to the adjacent ends of bars E F/ of each set, and mechanism foractuating bar F in the direction of its length, substantially asdescribed.

3. The co1nbination,with the bed-platehaving the series of ribs, of aseries of dies, each die connected to the frame by a series ofindependently-extensible bars constituting togglelevers, a longitudinalbar connecting the joints of the toggle-levers of each set, a springconnected to each die and to the frame for lifting the dies, a springconnected to each longitudi nal bar and to the frame for withdrawingsaid bars and iieXing the toggle-joints, and a series of cams arranged,as described, to actuate the longitudinal bars successively, but topermit their return simultaneously, substantially as described.
